Decisions, not tokens

A System One model reads your data once and answers every question with a probability, like a fast intuition you can measure.

Typed answers

Ask yes/no, choice and score questions. Every answer fits your schema by construction, because nothing is generated or parsed.

Calibrated confidence

Each answer is a full probability distribution with a confidence score, so thresholds actually mean something.

Milliseconds

One denoising step answers a whole set of questions. A typical request takes tens of milliseconds of model time.

Jev-compatible

The same wire API as TypeSafe's Jev. Their Python and TypeScript SDKs work unchanged; change the base URL.

Open all the way down

Open weights and an Apache-2.0 server. Anything you build on Codiv, you can also run on your own GPU.

Free to start

100M input tokens for every account during the beta. No card required.

Live

DiffusionGemma 26B-A4B turned into a System One model: the answer template goes onto the diffusion canvas and one denoising step reads a distribution for every answer.

More System One models

Codiv is built to serve any open System One model. New models and sizes will be added as open diffusion models land.
